Path Parameters
Response
Voided vendor bill
A vendor invoice (AP). Posts to AP and inventory/expense on approval.
Available options:
vendor_bill Sequential bill number per entity.
Vendor's invoice number.
Available options:
draft, pending_approval, approved, rejected, paid, partially_paid, voided bill_total minus amount_paid. Unlike the sales-side orders.balance_due, this is NEVER coerced to 0 by document lifecycle: a draft or terminal vendor bill still reports its true remaining payable. There is therefore no separate amount_due field on this resource. SSOT: utils/ap-helpers.mjs::updateAPBalance.
